2. Sarah is training for a triathlon. She is planning her training schedule and wants to know how much she should run each week. Her choices are to run 2 ¼ miles three times each week or she can run 1 ¾ miles five times each week. She wants to choose the option with the longest total distance. Which option should she choose? Explain your thinking in numbers and words.

Answers

Answer: She should run 1 1/3 miles 5 times a week.

Step-by-step explanation: I converted 3/4 to a decimal to have 1.75 and I multiplied it by 5 because that is how many times she will be running 1.75 miles in a week, I got 8.75. So that means if she runs 1.75 miles for 5 days she will run a total of 8.75 miles. Then I converted 1/4 into a decimal and now have 2.25, then I multiplied 2.25 by 3 and got 6.75. So I saw that 8.75 is greater than 6.75,

So the correct answer is: she should run 1 3/4 miles 5 times a week

Find the measure of the angle O. (Remember, you are finding the actual angle measure, not the ratio.)
Round to the nearest tenth.

Answers

Answer:

Θ ≈ 22.6°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosΘ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{12}{13}[/tex] , thus

Θ = [tex]cos^{-1}[/tex] ([tex]\frac{12}{13}[/tex] ) ≈ 22.6° ( to the nearest tenth )

Answer: (-4, 3)

============================================================

Explanation:

Starting at (4, -1) and moving four units up will have us arrive at (4, 3). We add 4 to the y coordinate and keep the x coordinate the same. The algebraic rule is stated as [tex](x,y) \to (x,y+4)[/tex].

Next, we reflect over the y axis. This will have us flip the sign of the x coordinate while keeping the y coordinate the same. The algebraic rule for this kind of reflection is [tex](x,y) \to (-x,y)[/tex]. The point (4,3) reflects over the y axis to get to (-4,3)

So we started at (4, -1), then moved four units up to get to (4,3) and then reflected over the y axis to get to (-4, 3) which is the final stop.

This is all shown in the diagram below.

The answer is 4, -3

im not sure about my answers please correct me if im wrong

Answer:

discrimnant: 120

Step-by-step explanation:

A) 350cm2
B) 1000cm2
C) 170cm2
D) 1200cm2

Answers

Answer:

1200 cm^2

Step-by-step explanation:

There are four 10 cm by 25 cm sides; the total area of these sides is

4 (10 cm) (25 cm) = 1000 cm^2.

There are two ends; the total area of these is 2 (10 cm) (10 cm) = 200 cm^2.

Thus, the total surface area is 1000 cm^2 + 200 cm^2, or 1200 cm^2 (Answer A).

55 men can finish a piece of work in 42 days. How many additional men must be added to complete the work 9 days earlier.

Answers

[tex]55 . 42 = x . 33\\55 . 14 = 11 . x\\x = 5 . 14 = 70\\70 - 55 = 15[/tex]Answer:

Step-by-step explanation:

The additional men required to complete this work 9 days earlier will be 15.

What is work time?

In time and work, we need to calculate the time required to complete a unit of work and find work done in a described period of time. Its known the amount of work done by a person varies directly with the time taken by them to complete the work on time.

Given that work was done by 55 men in 42 days

55 men ⇔ 42 days

Rate of work by 1 man ⇔ 1/(55×42)

Rate of work by 1 man ⇔ 1/(2310)

Now by adding N number of people the work need to complete 9 days earlier than 33 days.

Rate of work by 1 man ⇔ 1/[(55+N)×33]

Since the rate of work by 1 man will be the same for both cases

1/(2310) = 1/[(55+N)×33]

N = 15 hence,15 men additional required to complete the work 9 days earlier.

The midpoint of is point P at (−16,6). If point A is at (−10,8), what are the coordinates of point B? (−42,20) (−22,4) (−13,7) (2,−5)

Answers

Answer:

B (-22 , 4)

Step-by-step explanation:

-16=(-10+x)/2

*2 *2

-10+x=-32

+10 +10

x=-22

6=(8+y)/2

*2 *2

12=8+y

-8 -8

4=y

so B(-22, 4)

The coordinates of point B is (-22, 4).

What are the Coordinates?

Coordinates are the set of points in a geometrical plane or space, which is used to denote the exact point in the coordinate plane or space.

If we have the end points (x', y') and (x'', y'').

The mid point is ((x' + x'')/2, (y' + y'')/2).

Given that one of the end point A is at (-10, 8).

The mid point is at P(-16, 6).

Let the other point be B(x, y).

(-10 + x) / 2 = -16 and (8 + y) / 2 = 6

(-10 + x) / 2 = -16

⇒ -10 + x = -32

⇒ x = -32 + 10

⇒ x = -22

(8 + y) / 2 = 6

8 + y = 12

y = 12 - 8

y = 4

Hence the coordinate of the other point is B(-22, 4).

1. In this, we already know one side and one angle are congruent. For the triangles to be congruent by SAS, another side is necessary. Thus CB = FE

2. Here, we see that one set of sides are congruent. We see another set of angles are congruent as well. We also know that the center angle is congruent as the angles are formed by two straight lines intersecting. Since we see 2 next door angles and the side beside it congruent, they are proven congruent by AAS.
